hi guys,
im running out of pin now from my PICAXE (40x1).. i wanna do DAC using DAC0800.. ive tried MAX518 but i found it quite slow, so due to my problem lack of pin, so i'm deciding to use counter up/down using two 74LS193.. and it need only 3 pins (instead of 8 if i convert to use DAC0800) to count the MSB and LSB and then output from 74LS193 will be fed into DAC.. the only problem here is at the code... how do i separate that MSB and LSB and send it over to 74LS193??? is it binary or serial? mind to share a little code here?
